Awad (1) reported recently that the average firm experiences a 30% to 40% turnover in DP personnel because of voluntary resignations each year. We surveyed five of our client companies that use our Aptitude Assessment Battery: Programming test. One of these companies employs fewer than 50 programmers, two employ between 50 and 100 programmers, and the other two employ more than 100 programmers. The voluntary resignations in these five companies varied from a low of below one per cent to a high of 29%, with an average of less than 12%. The turnover rates due to inadequate capabilities for the work of programming in these companies varied from zero, in two of the companies, to a maximum of 5% with an overall average of less than 2%. The turnover rates due to unfavorable behavioral characteristics varied from zero to one percent.
